The Jazz wheels have a lip which fits round the hub when bolted up.
Any slight movement of the wheel on the hub is stopped by the lip. So any slippage is minimal and te ehub takes the strain -not the wheel bolts.
Of course, if I was driving a 500bhp monster and doing racing starts...
I have always used coppalsip/grease for over 50 years of driving and seen no evidence of damage to wheel threads.
Having thought about it a bit more, I'd assume the mention of "torque" above implies its the rotational load that is being considered. The lip will probably take lateral loads such as the weight of the vehicle and bump shocks.
The concern would thus be failure of the wheel studs in shear if they have to take all the acceleration or deceleration (such as emergency braking) forces as the wheel tries to rotate relative to the (lubricated) hub surface.
This, AFAIK, doesn't in fact happen, ever, even to me (touch wood).
Re what to use, as well as being relatively expensive where available, and unobtainable here in Taiwan, I don't like Coppaslip on (largely theoretical) electrochemical grounds. This probably wouldn't really be an issue with my steel wheels but might be with the alloys most people have.
I have a small tube of Aluslip, bought in Japan. I use it sparingly on things like exhaust manifold studs,
If cheapo chassis grease didn't do the job on hubs I might supplement it by rubbing with aluminium foil, but I've already painted the hubs with aluminium and sunflower oil (which set long ago so it doesn't stick my wheels on) so this would usually be overkill.
